The aim of this study is to see how the spinal sagittal configuration and mobility in 127 patients with idiopathic scoliosis are influenced by increasing scoliotic deformity and to determine when this deformity gets clinically significant compared to controls (n = 92). In patients with thoracic curves the degrees of thoracic kyphosis and lumbar lordosis were significantly less than those of the controls. Neither the kyphosis nor the lordosis were correlated to the Cobb angles. Even patients with small curves have straight spines in the sagittal plane; there is no tendency for the kyphosis and lordosis to decrease when the scoliotic deformity increases. This indicates that it is especially individuals with straight spines in the sagittal plane who are prone to develop scoliosis. It is also suggested that the limitation in spinal function for curves with Cobb angles below 50 degrees may be neglected.
本研究的目的是观察127例特发性脊柱侧凸患者的脊柱矢状面形态和活动度如何受到脊柱侧凸畸形加重的影响，并确定与对照组（n = 92）相比，该畸形何时具有临床意义。在胸弯患者中，胸椎后凸和腰椎前凸的程度明显低于对照组。后凸和前凸均与Cobb角无关。即使是小弯患者，其矢状面脊柱也是直的；当脊柱侧凸畸形加重时，后凸和前凸没有减小的趋势。这表明，尤其矢状面脊柱为直的个体更容易发生脊柱侧凸。还提示，Cobb角小于50度的脊柱侧凸对脊柱功能的限制可能可被忽略。
